Tiny, integrated FET solutions support nominal current levels of up to 5 A

DALLAS .- At the Applied Power Electronics Conference (APEC 2009), Texas Instruments Incorporated (TI) (NYSE:TXN) introduced three new hot-swap managers that help protect against over currents for voltage rails between 3 V and 20 V and an operating current of up to 5 A. The TPS2420 comes in a tiny 16-pin QFN package and the TPS2421-1 and TPS2421-2 come in 8-pin SOIC packages and offer more than twice the current throughput of existing hot-swap managers with integrated FETs in the same voltage range. For product details see: www.ti.com/tps2420-pr.

The TPS2420 family supports applications such as disk drive arrays, network clients, industrial monitoring devices and communications systems. The devices require up to 70 percent fewer external components than competitive products to implement a complete solution. Each device can operate across the entire operating voltage range with only the timing capacitor and resistor-set current thresholds.

The TPS2420 is available now in a QFN-16 package. The TPS2421-1 and TPS2421-2 will be available in second quarter 2009, in SOIC 8-pin packages. The TPS2420 is priced at $1.95 and the TPS2421-1 and TPS2421-2 are priced at $1.60, in quantities of 1,000.
